Watching and listening to these videos one after the other, one can compare the sounds of these two models. One has Casey’s Ergonomic Standard finger hole spacing, and the other his Ergonomic Small-Handed spacing. (He uses the term “Ergonomic” to indicate that some of the holes are slightly offset from the center line, as opposed to his “In-Line” option.)

Both are made of African blackwood. I think these are excellent instruments in the very affordable category of flutes ($450).

I have had a number of students with small or compromised hands. The Small-Handed Folk Flute model has made it possible for them to play comfortably, which is a great thing.
